" The Maxx M4A -PRO is an excellent Hopup unit. I installed it in an Umarex HK M110 A1. I had to use a Dremel and do some heavy modification to the M110's hopup adapter (the black polymer barrel extension that interfaces the hopup unit with the barrel) in order to get it to fit, as the stock hopup unit for the M110 is very slim and aftermarket hopup units don't fit. The Maxx M4A is a high quality, aluminum chamber, with clear side windows so you can see into the chamber. It has a nice BB retention system that prevents excess BB's from falling out when you remove the magazine. Very nice feature. The M4A comes with a flat nub installed and I used that with an R-Hopped barrel patch and smooth bucking. This setup is lifting .40g BB's and providing great range and accuracy in my rifle. Highly recommended.
" Went into my A&K SR-25 build with no issues at all. I’m a big fan of the bb retention, AMS has a mag limit and every bb counts.
" Have an M4A in an AEG build and an M4P in an HPA Jack build and they are both great. Easy to install and make small adjustments.
